Length Of Pack

Usually it is time for the patient to come out from his pack, when the
pulse becomes fuller and stronger, the face begins to flush and the head
to be affected. Frequently he sleeps till awakened by the increasing
heat. A drink of cold water will quiet him for a while, which may be
administered by means of a glass tube (julep-tube), in order not to
disarrange the pack by lifting him up. As long as the head is not
affected, there is no danger of his staying too long. The longer he can
stay, the surer the eruption will appear.
